Dear all,

I am simulating gas fludised beds using DDPM. I need to inject the particles directly at the first time step using a UDF.
I would be thankful to you if someone advice me or sharing UDF with me on this topic.

Thanks,

USERIN

if u r using DDPM for particle tracking then there is no need to use UDF to inject particles . you can use surface injection option in discrete phase model injections tab to inject all the particles in one time step.
